    For a common emitter circuit of a transistor, when the base current charges 80\[\mu \].i A, the collector current charges by 48 mA. The current amplification factor will be :

    A)  75                                         

    B)  50         

    C)  40                                         

    D)  60

    Correct Answer: D

    Solution :

                                                                The current amplifications factor is given by \[\beta =\frac{\delta {{i}_{c}}}{\delta {{i}_{b}}}=\frac{4.8\times {{10}^{-3}}}{80\times {{10}^{-6}}}=60\]
